[BUG, NEED FIX] Headshot %

I belive there is a big mistake with calculations of HS %. I thought that my 90% of kills were headshots because i only tap in this game, never spray. For example there is a match where noone had more than 42% hs. Like people have 20% 22%, and me only 39% where it should be minimum 60%. Can someone explain it to me? It supposed to calculate how many kills that you’ve made were executed by Headshot, correct?
